Description
Technical Field
The utility model relates to a railway and urban rail transit field, concretely relates to detect empty measuring device who hangs value between rail and sleeper and ballast stone.
Background
Nowadays, rails are mainly composed of rails, sleepers (wooden, concrete and steel), track beds, switches and connecting fasteners. Meanwhile, the connecting fastener system is generally composed of an iron backing plate, an elastic strip, an elastic backing plate, an anchoring system, etc., and the fastener having the iron backing plate is generally referred to as a base plate type fastener, and the iron backing plate used therefor may be referred to as a base plate. The double layer fastener typically includes an upper iron backing plate, which may also be referred to as a rail plate, and a lower iron backing plate, which may be referred to as a base plate. While a single layer fastener comprises only one layer of iron backing plate, which may be referred to as a rail plate or a baseplate. The rail bearing plate has four sides, the two sides of the rail bearing plate corresponding to the two sides can be called as the left side and the right side of the rail bearing plate, and the two sides perpendicular to the laying direction of the steel rail are the front side and the back side. The elastic strip mounting seat is connected to the rail bearing plate or integrally formed with the rail bearing plate. When the iron base plate and the gasket are worn or the torque force of a connecting part is insufficient and fails, after the train wheel presses the rail, a hanging plate can be generated between the bottom of the rail and a rail bearing groove of the sleeper, ballast stones at the bottom of the sleeper are not tamped in real time, a gap can be generated between the bottom of the sleeper and the ballast stones, and the height of the gap and the hanging plate and the air-to-air hanging value are obtained. Accurate empty distance of hanging is mastered in actual measurement, just can be timely carry out better maintenance to the track frame, guarantees the train safety of traveling. Currently, no special measuring instrument can measure the empty hoisting value of the sleeper after the train passes by, and workers usually carry out visual estimation through experience, so that the obtained empty hoisting value is inaccurate, the maintenance of a track frame is influenced, and the running safety of the train is endangered.
